Overview
Series D Hydraulic Gear Pumps
Technical Manual
General information
The D Series pumps have an excellent reputation for rugged, dependable performance
at continuous pressures to 276 bar [4000 psi] and speeds to 3400 min-1 (rpm). Typical
noise level is less than 75 dB(A) under normal operating conditions.
The D Series pumps provide tremendous design flexibility. They have standard
displacements from 7 to 45 cm³/rev [.43 to 2.75 in³/rev]; splined, keyed, and tapered
shaft drive options; SAE porting; and integral valve options that can be used in virtually
any combination to create a pumps that meet specific application requirements.
The cast iron housings that comprise the pump structural members provide the strength
needed for rugged applications. The front mounting flange and cover are ductile iron
members that incorporate, and solidly support, the heavy-duty journal bearings. These
bearings are state-of-the-art steel-backed bronze, developed for just the type of pressure
the D pumps can handle. The center gear plate section (also made of ductile iron) is the
main pressure vessel of the pump, and is designed for maximum strength.

Series D Hydraulic Gear Pumps
Technical Manual
General information
One piece gear construction
All D Series pump gear shafts are of one-piece construction. This enables the shaft to
provide uniform high strength and accurate gear profile relative to the journals for
smooth mesh operation. This design controls all gear tolerances, in particular total radial
run-out of the gear and gear face parallelism. The integral gear shafts are constructed
of heat-treated AISI 8620 steel manufactured to precise tolerances and surface finishes
for maximum life and minimal leakage. This integral design eliminates the potential
problems of fatigue stress and gear face mismatch often associated with two-piece gear
shaft designs.
Sealing
An important feature of all modern hydraulic gear pumps is the method of sealing the
sides of the rotating gears for efficient operation over a wide temperature range. The
fixed clearance gear pump, which has benefits of its own, has long been discounted for
most applications requiring high efficiency, since only very close clearance can control
side leakage paths.
The D Series pump sealing function incorporates steel-backed bronze deflecting plates,
which fit into conforming depressions in the mounting flange and cover (and in the
bearing plate for multiple pumps). The deflecting plates seal the sides of the gears.
The key to this function is the pressure-loading load seal underneath one plate on the
mounting flange side. The pressure-loading seal, incorporating a Viton® elastomeric
element and a flexible anti-extrusion element, allows discharge pressure underneath
the plate to balance the pressure distribution in the gear tooth spaces, with a slight
overbalance to keep the thrust plates sealing against the sides of the gears.
Pressure balanced deflecting plate
This design, often called a deflecting-plate gear pump, offers pressure balanced side of
the gears in a compact package size. The deflecting plates provide uniform side sealing
of the gears over the wide range of pressures and temperatures. The deflecting plates
are constructed of steel-backed bronze.
Advantages
• Up to 276 bar [4000 psi] operating pressure
• Power density: 20% smaller envelope size than conventional pumps
7 to 45 cm³ [.43 to 2.75 in³/rev] in one frame size
• Flexibility: Integral valve options, multiple sections, and reduced or common inlets
for numerous configurations
•
High Efficiency: 96% volumetric, 90% overall

Valve options
Fixed priority flow valve
D series pumps are available with an optional fixed orifice Priority Flow Divider (PFD)
valve integrated into the rear cover. The PFD valve divides the flow and provides a fixed
amount of flow to the Controlled Flow (CF) port for priority functions such as steering.
The remaining flow is routed to the Excess Flow (EF) port for additional functions such as
directional control valves and fan drives.

Priority flow is pressure compensated, therefore priority flow is independent of excess flow working pressures.
The priority flow is factory set and can deliver 7.6 to 34.1 l/min (2 to 9 US gal/min).
The priority circuit has an integral, direct acting pilot relief valve with internal drain. Settings range from 34 to 172 bar (500 to 2500 psi).
The D series PFD can be used in tandems and other multiple pump configurations, but only in the rear pumping section.
Rear and side porting options are available.

Valve options
Load sense priority flow valve
D series pumps are available with an optional Load Sense (LS) priority valve integrated
into the rear cover. The LS priority valve supplies priority flow on demand to functions
such as load sense steering, while the Excess Flow (EF) is available for secondary functions
such as directional control valves and fan drives. A load sense signal line from the priority
circuit to the gear pump’s LS port governs flow to the primary circuit. As the load sense
signal pressure increases, priority (CF) flow also increases. When the controlled function is
idle (no load sense demand), full pump flow is available for the secondary functions.

The D series LS priority valve is available with 40 l/min [10 US gal/min] and 80 l/min [21 US gal/min] flow settings.
The priority circuit is available with an optional integral direct acting pilot relief valve with internal drain. Pressure settings range from 34 to 172 bar [500 to 2500 psi].
The load sense valve is dynamic and has a constant flow of 0.5 to 1.0 l/min
[0.13 to 0.26 US gal/min] present at all times to ensure fast reaction.
The D series PFD can be used in tandems and other multiple pump configurations, but only in the rear pumping section.
Rear and side porting options are available.

System specifications
Definitions of the D Series operating parameters appear below. Consult Turolla OCG
technical support for applications running outside of these parameters.
Line sizing
Recommended fluid velocities
Inlet
4.3 m/sec [14 ft/sec]
Inlet conditions should be reviewed
Discharge 8.0 m/sec [18 ft/sec]
to minimize inlet oil velocity and inlet
vacuums. This will result in quieter
system operation, reduced operating
temperatures and longer pump life. To avoid pump cavitation, the maximum inlet line
flow should not exceed 4.3 m/sec (14 ft/sec). Discharge velocity should be limited to 8
m/sec (18 ft/sec).
Inlet pressure
Continuous inlet vacuum should not
exceed 0.8 bar absolute (6.3 in Hg).
During cold starts, a vacuum of 0.6 bar
absolute (12.2 in Hg) can be tolerated for
short durations.
Rated pressure
D series pumps are designed to
operate continuously at rated pressure.
Operating at or below this pressure will
yield satisfactory product life.
Peak pressure
Peak pressure is the highest
(intermittent) pressure allowed and is
determined by the relief valve reaction
overshoot. Peak pressure is assumed to
occur for less than 100 ms in duration.
Inlet pressure
Recommended minimum
0.8 bar absolute

Maximum speed ratings
The maximum speed is the highest recommended operating speed. Maximum speed
ratings assume operation within recommended inlet pressures and use of quality ISO
VG46 hydraulic fluid. Operating at or below this speed will yield satisfactory product life.
Minimum speed ratings
Minimum speed is the lower limit of operation and is a function of discharge pressure
and fluid temperature.

Series D Hydraulic Gear Pumps
Technical Manual
System specifications
Fluids
Catalog ratings for D series gear pumps are based on operation with a premium
hydraulic fluid containing oxidation, rust, and foam inhibitors. The fluid must possess
good thermal and hydrolytic stability to prevent wear, erosion, and corrosion of internal
components. Consult Turolla OCG technical support before using non-petroleum based
(including water glycol), fire-resistant, or biodegradable fluids. The use of these fluids
may require special seal materials and/or specially designed hardware.
For more information on hydraulic fluid selection, see Turolla OCG publications
520L0463 Hydraulic Fluids and Lubricants, Technical Information, and 520L465 Experience
with Biodegradable Hydraulic Fluids, Technical Information.
Temperature
Temperature limits
Minimum, cold start -30 °C [-20 °F]
Temperature and viscosity requirements
Maximum continuous 82 °C [180 °F]
must be concurrently satisfied. The
Peak (intermittent)
104 °C [220 °F]
pump should be run at or below the
maximum continuous temperature.
The peak temperature is based upon material properties and should never be exceeded.
Cold oil will generally not affect the durability of the pump, but it may affect the ability
to flow oil and transmit power. Ideally, the lowest expected oil temperature should
remain at least 16C (30F) above the pour point of the fluid.
Viscosity
Minimum viscosity should be
encountered only during brief occasions
of maximum ambient temperature and
severe duty cycle operation.
Fluid viscosity
limits mm²/sec (cSt) [SUS]
Minimum, intermittent 10 [60]
Recommended range
12 to 60 [66 to 290]
Maximum, cold start
1600 [7500]
The maximum viscosity should be encountered only during cold start. Limit the
operating speed until the fluid warms up.

Filtration
To prevent damage to the pump, including premature wear, fluid entering the pump
inlet must be free of contaminants. D series pumps require system filtration capable of
maintaining fluid cleanliness at ISO 4406-1999 class 22/18/13 or better.
Turolla OCG does not recommend suction line filtration. Suction line filtration can cause
high inlet vacuum, which limits pump operating speed. Instead we recommend a 100
micron screen in the reservoir covering the pump inlet. This protects the pump from
coarse particle ingestion.
Return line filtration is the preferred method for open circuit systems. Consider these
factors when selecting a system filter:
•
•
•
•
Cleanliness specifications
Contaminant ingression rates
Flow capacity
Desired maintenance interval
Typically, a filter with a beta ratio of β = 10 is adequate. However, because each system
is unique, only a thorough testing and evaluation program can fully validate the filtration
system. For more information, see Turolla OCG publication 520L0467, Design Guidelines
for Hydraulic Fluid Cleanliness.
10
Reservoir
The reservoir provides clean fluid, dissipates heat, and removes entrained air from the
hydraulic fluid. It allows for fluid volume changes associated with fluid expansion and
cylinder differential volumes. Minimum reservoir capacity depends on the volume
needed to perform these functions. Typically, a capacity of one to three times the pump
flow (per minute) is satisfactory. Locate the reservoir outlet (suction line) near the
bottom, allowing clearance for settling foreign particles. Place the reservoir inlet (return
lines) below the lowest expected fluid level, as far away from the outlet as possible.

Pump drives
Series D Hydraulic Gear Pumps
Technical Manual
System specifications
Pump drive
D Series pumps can be direct-driven by tapered, straight keyed or splined drive. They are
well suited for external gear or pulley drive. Gear drive for the pump can be by spur or
helical gear.
Contact Turolla OCG technical support for all non-standard direct-driven and all geardriven or pulley-driven applications. The figures on the next page show the information
Turolla OCG requires to analyze applications using a gear or pulley drive. From this
information, Turolla OCG determines:
•
If the drive method is feasible
•
Optimum range of angles for driving the pump or motor
•
Pressure limitations, if any, for applications where the drive angle is customer
specified
•
Helical gear thrust load and its effect on the pump
Use a spring-loaded belt tensioner in belt drive designs.
Plug-in drives
Plug-in drives are acceptable only with a splined shaft. Plug-in drives are acceptable
if the concentricity between the mating spline and pilot diameter is within 0.1 mm
[.004 in.] If a plug-in drive is used, lubricate the spline drive with flowing oil. Use an
intermediate coupling to minimize radial or thrust shaft loads.
Have Turolla OCG technical support review any known thrust or radial loads on
the pump drive shaft. We need to know if the load is stationary or rotates with the
shaft (typical of an imbalanced load). Radial external load-handling capability is
excellent in D Series pumps, but it should be minimized.
In applications where you can’t avoid external shaft loads, optimize the orientation and
magnitude of the load on the pump to minimize the impact. Don’t use splined shafts for
belt or gear drive applications. Use a tapered input shaft for all gear and pulley drives.
